Novel Way to Treat Chronic Kidney Disease and Heart Failure Identified

Researchers by using stem cells have discovered a new way of treating chronic kidney disease and heart failure in rats.

Dr. Darren Yuen and Dr. Richard Gilbert were the first to show, in 2010, that enriched stem cells improved heart and kidney function in rats with both diseases.

Acute Renal (Kidney) Failure- Causes, Symptoms, Diagnosis, Treatment and Complications
Acute renal failure is the sudden cessation of the functioning of kidneys, that can be due to reduced renal blood flow, damage to renal tissues.

But they and other scientists wondered about the potential side effects of returning those cells to the body, such as forming tumours.

In a paper published online today in the journal Stem Cells, Drs. Yuen and Gilbert said they have since found that enriched bone marrow stem cells secrete hormones in the petri dish that, if injected into rats, has the same positive impact as the stem cells.

"We've shown that we can use these hormones, collected in the dish, to replicate the beneficial effects of the stem cells in treating animals with chronic kidney disease and heart failure," said Dr. Yuen, a nephrologist. "In our view, this is a significant advance for stem cell therapies because it gets around having to inject stem cells."

Congestive Heart Failure (Congestive Cardiac Failure) Current Management
Congestive heart failure (CHF) is a condition in which the heart fails to work adequately as a pump that can deliver oxygen rich blood to the body.

Dr. Yuen said they do not yet know what kind of hormone the cells are secreting. Identifying the hormone would be the first step toward the goal of developing a synthetic drug.
